hmm ok thanks! And when you do the long division, what exactly is the equation of the line? Does it include the remainder or do I omit that? Eg after doing long division if I got 2x-1 r 3, then what is the equation of the oblique asymptote?

For question 12d, how do I find the SECOND derivative? My answer is coming out sorta different.. it's just deriving it again right? The answer for 12 d second derivative is 4t^3 /(1+t^2 )^3

Thanks so much man :) :) :)

Apparently you use long division, but is there another way? Thanks :)

Fankks brooo(s)!!

Ok..so if I wanna prove question 10a, what do I write for d/dx? :(

Hey, can someone give me worked solutions to 12b? thanks

Can you give me an example? Like for a function: y= 2x^3 + 4x^2 -7x + 9 What would d/dx be? That way it'll make more sense

What on earth does d/dx mean? What the difference with dy/dx? Look at these questions and you'll see what I mean

I need some help with 3 e, the limit thing :) thankss

The interval PQ has length p, and the point A lies between the points P and Q. Find PA when PQ × QA = PA^2

Thanks a tonne guys!

The curve y = ax^2 + bx + c touches the line y = 2x at the origin and has a maximum point when x = 1. Find the values of a, b and c. ANSWER a=-1, b=2 c=0

Self-learning maths isn't always easy as you may miss a few key points and stuff. It's better to have someone explaining stuff to you. Maths is that kind of subject.

the curve y=ax^3 +bx^2 -x+5 has a point of inflexion at (1, -2). Find the values of a and b. Sorry I know this is probs a dumb question haha

Possible, but your bio rank might cause some problems. You might be close though

Yeah trueess. But then again if i wanna get good i needa know depth right? That's where memorising the features comes in.

I use Riley. Is that sufficient?

I'm only on chapter 2 yet I'm freaking out on how to actually remember all this stuff. It just goes on and on and the info is endless. HELP!!!! How do I eventually remember all this stuff?

Fuarrrrrrr this shitty textbook drives me crazzyyyy. obviously been written by an extension maths wannabee. Repetitive questions and those retarded side notes. One of those stupid side notes even said: "Perimeter is the sum of the sides" --- the heckk Maths in Focus should be banned from High...
